Title: Solid lime-sand bricks for building use - contg. perlite to reduce density and increase thermal insulation
Inventor: HANNEMANN GERHARD
IPC: C04B28/20
Filed: 1974-09-14
Abstract: Lime-sand bricks as solid stones for use as wall bricks using dosed weights of sand, burnt lime and water with intensive mixing and passage through a reactor in which the CaO is converted to Ca(OH)2, and the mixt. is then moulded at high press. into brick-blanks hardened in an autoclave. Prior to pressing, another constituent is added to the mixt. viz. a granulated crude stone product which has been cooled to a very low temp. pref. -160 degrees C or enriched with milk or cement. The crude stone product is pref. perlite, which reduces the density of the solid bricks and improves the thermal insulation.

Title: Charging of secondary cells or batteries - uses appts. consisting of current source, rectifier and regulator responsive to battery EMF
Inventor: WEBB GEOFFREY JAMES
IPC: H02J7/10
Filed: 1975-02-04
Abstract: The charging circuit, for secondary cells, has a semiconductor switch between supply rectifier and battery, controlled by a comparator. The comparator compares a Zener diode reference voltage with the battery open circuit e.m.f. The comparator controls the semiconductor control switch such that the rectifier is disconnected from the battery whenever the instantaneous open circuit e.m.f. reaches 110% of the battery or cell nominal open circuit e.m.f. To prevent individual cells within a battery being overcharged, the open circuit e.m.f. of each cell is monitored by a second comparator which also controls the semiconductor switch, and e.g. a warning system.

Title: Transfer dye printing process - uses controlled vacuum pressure to allow use of temperatures below softening point of synthetic fibres in fabric
Inventor: PABST MANFRED DIPL ING
IPC: D06B11/00
Filed: 1975-11-22
Abstract: Process for dyeing and printing woven and knitwear by a transfer action, where the material is composed (partly) of synthetic fibres, by the application of heat to evaporate the dyestuff on a carrier paper for transfer to the fabric. The printing paper is placed in contact with the fabric and passed into the gap between the mantle of a heated drum and an impermeable continuous belting passing partially round it. The underpressure in this gap zone is regulated according to the rate of dyestuff diffusion, and reduced to the point where the colour travels from the carrier paper to the fabric at a temp. which is below the softening temp. of the synthetic fibres passing round the drum. The process allows transfer printing of synthetic fibres as the control of underpressure and heat ensure that the dyestuff travels from the carrier to the fabric, without the character of the material being damaged by the process.
